The plan of the base in Fig. 180 shows that the maximumstresses in the rods and struts occur when the wind is blowingagainst the side of the tower. The maximum stresses in columnsoccur when the wind is blowing diagonally across the tower andare of the amounts obtained from the diagram. The windforce is not the result of a constant load, so in a number of specifi-cations only 80 per cent of the maximum wind force is considered. The wind acts at the top through the center of gravity of thefilled tank, and at the joints on the side of the tower. In the COLUMNS AND STRUCTURES 279 tower diagram dotted lines are shown, transmitting the windfrom the tank to the frame. In the stress diagram the upHft ismeasured from / to I. The tower loads are all positive (compres-sion). In the tower diagram dotted counters
